To access the global water levels of lakes and rivers
Defined as the height, in meters above the geoid, of the reflecting surface of continental water bodies
Water scarcity and transboundary issues on water resources
The data was collected by observation using space radar altimeters that measure the time it takes for radar pulses to reach the ground targets, directly below the spacecraft (nadir position), and return. Water Level is computed as time series over lakes and at the intersections of rivers and the satellite ground tracks
